Which additive manufacturing process is known for high precision and intricate designs?

Stereolithography (SLA) is renowned for its ability to produce high-precision parts with intricate designs. This success is largely due to the process's reliance on ultraviolet (UV) light to cure liquid resin layer by layer, allowing for fine details and smooth surface finishes.

SLA's capability to create complex geometries and replicate intricate features makes it ideal for applications requiring a high level of detail, such as prototypes, dental models, and detailed figurines. The layer thickness can often be much thinner compared to other additive manufacturing methods, enhancing the precision of the printed components.

While other methods like Fused Deposition Modeling (FDM) and Fused Filament Fabrication (FFF) may be used to produce functional parts, they typically face limitations in precision and surface finish due to the nature of their extrusion process. Binder Jetting, while versatile, does not focus primarily on fine details and precision to the same extent as SLA. Thus, SLA is the clear standout choice for high-precision requirements in additive manufacturing.
